' IMPROVEMENT IN APPA RATUS FOR ADJUSTING MOSQUITO-BARS.

Specification forming part of Letters Patent No. I 7 1,400, dated March7, 1876; application filed December 27, 1875.

To all whom it may concern Be it known that I, IsAAo ATWOOD ABBor, ofNew Orleans, in the parish of Orleans and State of Louisiana, haveinvented a new and Improved Mosquito Bar Adjusting Apparatus, of whichthe following is a specifioation Myinvention'consists of a small pulleynear each foot and corner of the tester, on the under side, throughwhichrun cords-connecting with the traveling rod, and running throughother pulleys at the head of the bed,

ing rod, run directly to the pulleys at the head of the bed, andterminate in a hanging knot or tassel for pulling the traveling rod upto the head of the bed, for gathering upv the netting thereat when it isnot required -to be spread. The object is to provide contrivance wherebythe netting can be worked more conveniently and with less'damage, bylocal strains than it Figure l is a side elevation of the apparatus forsuspending and adjusting the mosquitobar. Fig. 2 is a horizontalsection. Fig. 3 is a sectional elevation; and Fig. 4 is a perspectiveview of one of the pulley-blocks.

'Similar letters of reference indicate corresponding parts.

A represents the bar or 'net, which is suspended from the rod B, andalso from the traveling rods D, which slides backward and 4 forward onrods B, and is actuated by cords G and O, the rods 0 being extendeddirectly from it to pulley-block F, through which they pass, one of themgoing through the guidepulley E. From the block F they are suspended soas to be reached readily for gathering up the bar at the head of thebed. The cords 0 pass from the traveling rod to the foot end of the bed,where they pass around guide-pulleys E, and then go back throughpulley-blocks F, and are suspended from the same as the others, forpulling the bar from the head to the foot of the bed, thus making asimple and efficient contrivanoe for working the bar.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- The combination of cords O 0', guidepulleys E and E,and the pulley-block F with the traveling rod of a mosquito-bar frame,substantially as specified.
